Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tunnel construction equipment, in particular to a small-section tunnel pressure steel pipe transportation tool. BACKGROUND

[0002] In the water diversion system of a hydropower station, water flow is mainly transported through a pressure steel pipe, and the water in a reservoir, a forebay or a surge tank is guided to a generator set through a tunnel to drive a water turbine to rotate, thereby generating electricity. The pressure steel pipe can be roughly divided into three types, namely, small, medium and large types (also referred to as small section, medium section and large section) according to its diameter range. The diameter range of the small pressure steel pipe is generally between 0.5-2m, the medium pressure steel pipe is between 2-5m, and the large pressure steel pipe is more than 5m.

[0003] When the medium and large pressure steel pipes are transported, a special transportation platform is often needed, and the transportation of the small pressure steel pipe mainly relies on an ordinary transportation flat car. In order to prevent the pressure steel pipe from rolling during transportation, an anti-rolling support is generally installed on the transportation flat car. The common anti-rolling support has a concave structure, and the width thereof cannot be adjusted. When the diameter of the pressure steel pipe to be transported changes, a corresponding size of the anti-rolling support needs to be re-made, which is relatively troublesome. Further, since the pressure steel pipe is heavy, improper handling during transportation can easily cause the pressure steel pipe to overturn. To prevent the pressure steel pipe from overturning, two points need to be ensured, that is, the first point is to reduce the center of gravity of the pressure steel pipe as much as possible, and the second point is to ensure the uniformity of the distribution of the weight of the pressure steel pipe on the transportation flat car. The installation quality of the anti-rolling support directly affects the distribution of the weight of the pressure steel pipe. Therefore, the repeated disassembly and assembly of the anti-rolling support can easily increase the safety risk during transportation. CONTENT OF THE UTILITY MODEL

[0004] To solve or partially solve the problems in the related art, the present application provides a small-section tunnel pressure steel pipe transportation tool.

[0028] Reference Figs. 1-3 A small cross-section tunnel pressure steel pipe transportation tool comprises:

[0029] The transport flat car 1 mainly comprises four parts, a load platform 11 for loading goods, wheels 12 for moving, jacks 13 for keeping the load platform horizontal, and a connecting frame 14 for connecting the car head, and the specific structure is the prior art, which will not be described here.

[0030] The baffle 2 is arranged at one end of the load platform 11 close to the cab, and a reinforcing plate 21 is arranged on the side of the baffle 2 to improve the impact resistance of the baffle 2. During loading, one end of the pressure steel pipe 6 is tightly attached to the baffle 2. When an emergency occurs during transportation and needs to be stopped urgently, the impact of the pressure steel pipe 6 can be resisted by the baffle 2, avoiding the sliding of the pressure steel pipe 6 to the cab under the action of inertia, and ensuring the safety of the cab.

[0031] The support 3 is arranged in multiple, uniform and fixed on the load platform 11, and the installation mode can be selected from common fixing modes such as welding and bolt connection. An arc-shaped groove 31 is opened at the middle position of the support 3, and the curvature of the arc-shaped groove 31 is greater than the curvature of the outer diameter of the pressure steel pipe 6, so that when the pressure steel pipe 6 is placed in the arc-shaped groove 31, it can naturally stand at the middle position of the support 3 under the action of gravity. Further, referring to Fig. 2 When the support 3 is installed, the lowest point of the arc-shaped groove 31 needs to be located at the center line position of the transport flat car 1, so as to ensure the uniformity of the weight distribution of the pressure steel pipe 6.

[0032] The locking assembly 4 comprises guide strips 41 and clamping plates 44. Two guide strips 41 are installed in parallel on the load platform 11 through reinforcing bolts 42, so that an adjusting groove 43 is formed between the two guide strips 41, and two adjustable clamping plates 44 are symmetrically installed in the adjusting groove 43. After the pressure steel pipe 6 is placed on the support 3, the clamping plates 44 are clamped on both sides of the pressure steel pipe 6 respectively, so as to fix the pressure steel pipe 6 and prevent the pressure steel pipe 6 from rolling during transportation. The specific fixing mode of the clamping plate 44 is that wing plates 45 are arranged on both sides of the clamping plate 44, and fixing bolts 46 are screwed with the guide strips 41 after penetrating through the wing plates 45, so as to fix the wing plates 45. Since the specifications of the pressure steel pipes 6 to be transported in the same batch are usually consistent, the position of the clamping plate 44 only needs to be adjusted during initial use. When the diameter of the pressure steel pipe 6 to be transported changes, the position of the clamping plate 44 can be adjusted and fixed again by re-drilling holes on the guide strips 41, which is convenient and fast. Since the position of the clamping plate 44 can be adjusted according to requirements, no matter how the diameter of the pressure steel pipe 6 changes, the bottom surface of the pressure steel pipe 6 can always be in contact with the support 3, preventing the bottom of the pressure steel pipe 6 from being suspended due to the increase in the diameter of the loaded pressure steel pipe 6, so as to ensure that the center of gravity of the pressure steel pipe 6 is always at a low position, and improve the safety during transportation.

[0033] In some embodiments, the hooks 5 are evenly arranged on both sides of the carrier platform 11, and when the pressure steel pipe 6 is fixed, the pressure steel pipe 6 can be bound by a bandage, further ensuring the stability of the pressure steel pipe 6, and the hooks 5 on both sides can be used as winding points of the bandage.

[0034] Finally, it should be noted that in this document, relationships such as first and second, and the like, are merely used to distinguish one entity or action from another, and do not necessarily require or imply any actual relationship or order between or among such entities or actions. Moreover, the terms including, including, or any other variant thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements is not limited to those elements, but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.

Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments.
